[rules-users] Multi-user architecture of Drools Web Service.

[Mauricio Salatino]

It depends on how are you exposing web services or the component behind
those web services..
If you use a Stateful Session Bean, this component will do all the work for
you. But if your services are stateless by nature, you need to implement the
mechanism. You can implement this mechanism in two ways: In messages (adding
a session id that goes and come back with the response) or in server side
with a client id.

>>>  Hi,
>>> what I have is SOAP Web Service with two methods: fn_AddFacts, and
>>> fn_Conclude. I defined special XML implementation to send various fact's
>>> types via SOAP. Model is defined in DRL/Guvnor - and rules too.
>>>
>>> So now, I can add some facts (web service creates them using Drools
>>> "reflection" API) to knowledge base. And then use fn_Conclude method, to
>>> fire "fireAllRules" method and get response with results. But.....
>>>
>>> What if now I have 100 users, and I don't want their's facts to interfere
>>> each other? I want, to use Drools to conclude for different users. I want to
>>> use this same rules, but on different knowledge bases (each user has own
>>> knowledge base of his facts).
>>>
>>> Please help me, how to solve this problem... I am new in JAVA EE, and I
>>> don't understand some elementary issues well. (But I am trying to understand
>>> them :D )
>>>
>>> regards,
>>> tom.
